ALNUR — Open-source end-to-end vulnerability identifier for applications

ALNUR

Open-Source End-to-End Vulnerability Scanner

ALNUR is an open-source, end-to-end security vulnerability scanner for application projects. Point it at any project directory and it acts as your security analyst — detecting CVEs in dependencies, leaked secrets, architecture flaws, standards violations, risky port configurations, and — uniquely — security risks in agentic AI applications.

Features

Module	What It Checks
CVE Scanner	Queries OSV.dev for known CVEs across all detected packages
Secret Detection	Finds hardcoded API keys, tokens, passwords, and private keys using patterns + entropy analysis
Architecture Analysis	30+ SAST rules covering injection, weak crypto, insecure deserialization, misconfigurations
Agentic AI Analysis	30 rules targeting LLM/agent-specific risks: prompt injection, excessive tool permissions, unauthenticated endpoints, exfiltration combos, MCP misconfigurations
Standards Compliance	Gitignore hygiene, lockfile presence, CI/CD, test suite, Docker best practices
Port Risk Analysis	Flags dangerous ports in Dockerfiles, docker-compose, config files, and .env
LLM-Enhanced Analysis	Optional AI-powered executive summary and remediation guidance (OpenAI / Anthropic / Groq / Mistral / Ollama)

Risk Grading

Grade	Score	Meaning
A	0–19	Low risk — keep it up
B	20–49	Minor issues — review low-priority findings
C	50–99	Moderate risk — address before production
D	100–199	High risk — urgent remediation needed
F	200+	Critical — do not deploy

Output Formats

• Console — Rich colored terminal output with tables and severity badges
• JSON — Machine-readable structured report (CI/CD integration)
• HTML — Self-contained dark-theme security dashboard, no external dependencies

Exit Codes

Code	Meaning
0	Scan completed — no critical/high issues
1	Critical or high severity issues found

CVE Data Source

ALNUR uses the OSV.dev API — a free, open vulnerability database covering npm, PyPI, Maven, NuGet, RubyGems, crates.io, Packagist, Go modules, and more. No API key required.

Agentic AI Security

ALNUR automatically detects files that import LangChain, CrewAI, AutoGen, LlamaIndex, OpenAI Agents, Anthropic SDK, and other agentic frameworks, then applies 30 dedicated rules:

Rule Range	Category	Severity
AGENT001–004	Secrets in agent context / hardcoded LLM keys	HIGH/CRITICAL
AGENT005–007	Prompt injection surfaces	CRITICAL
AGENT008–014	Excessive tool permissions (shell, filesystem, SQL, email)	HIGH/CRITICAL
AGENT015–016	Unauthenticated agent endpoints	CRITICAL
AGENT017–018	Data exfiltration combos (DB + outbound HTTP)	HIGH
AGENT019–022	MCP server misconfigurations	HIGH/CRITICAL
AGENT023–030	Missing human-in-the-loop, unsafe delegation, code execution	HIGH/CRITICAL

Optional LLM-Enhanced Analysis

Set any supported API key and ALNUR will automatically include an AI-generated security review at the end of each scan — no extra flags needed.

Environment Variable	Provider	Default Model
OPENAI_API_KEY	OpenAI	gpt-4o-mini
ANTHROPIC_API_KEY	Anthropic	claude-haiku-4-5
GROQ_API_KEY	Groq	llama-3.1-8b-instant
MISTRAL_API_KEY	Mistral	mistral-small-latest
OLLAMA_HOST	Ollama (local)	llama3.2

Override any setting with environment variables:

export ALNUR_LLM_PROVIDER=anthropic    # force a specific provider
export ALNUR_LLM_MODEL=claude-sonnet-4-6  # override the model
export ALNUR_LLM_BASE_URL=http://...   # custom endpoint / proxy

Use --no-llm to disable the feature even when a key is present.

Architecture Rules (Sample)

Rule	Category	Severity
INJ001–009	SQL / Command Injection	HIGH/CRITICAL
DESER001–003	Insecure Deserialization	HIGH
CRYPTO001–004	Weak Cryptography	MEDIUM/HIGH
TLS001–004	SSL/TLS Misconfiguration	MEDIUM/HIGH
DJANGO001–005	Django Misconfiguration	MEDIUM/HIGH
FLASK001–003	Flask Misconfiguration	MEDIUM/HIGH
NODE001–004	Node.js Misconfiguration	MEDIUM/HIGH
DOCKER001–003	Container Security	MEDIUM/HIGH
XSS001–002	Cross-Site Scripting	HIGH
PATH001–002	Path Traversal	HIGH

Suppressing False Positives

Add # alnur: ignore to any line to exclude it from all scan results:

API_KEY = os.environ.get("API_KEY", "default-value")  # alnur: ignore
